WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 334,057, dated January12, 1886.

Application filed December 3, 18F5. Serial No. 184,633. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM N. SPRINGER,

a citizen of the United States, residing at Indianapolis, in the countyof Marion and State ofIndiana, have invented anew and useful Improved\Vagon-Jack, of which the following is a specification.

My invention relates to that class of liftingjacks known as wagon-jacks,and it consists in the construction and arrangement of parts in themanner hereinafter fully specitied. I

The accompanying drawings illustrate my invention.

Figure l is a side elevation showing the parts in position to receivethe wagon-axle; Fig. 2, a similar view showing the position of the partswhen the wagon is raised, and Fig. 3 a front elevation.

The bodyof thejack consists of a vertical wooden post, a, framed into ahorizontal footpiece, I). A pair of semicircular metal plates, like 0,are secured at their ends, one on each side, to the foot-piece Z) bybolts (Z d, and to the vertical post bya bolt, 0. Said plates formbraces for the vertical postand foot-piece, and also points of pivotalattachmentlor the levers f and g,which are secured between said platesby bolts h and i.

J is a sliding support for the wagon-axle, having secured to itsopposite sidesa pair of plates, k, which engage a pair of verticalgrooves, Z, in opposite sides of post a, the purpose being to hold saidaxle-support against 5 the face of the post and permit a vertical slid-'ing movement thereon. Said plates is are provided with a series ofholes, m. which pass also through the support J, and are for the purposeof connecting the support at differ- 0 cut points with a pair of arms, an, by means of a pin, 0. The free ends. of arms n are pivotallyconnected to thefree end of lever g, and form therewith thetoggle-joint, which is operated by means of leverf and a pair of con- 5meeting-rods, like 1), there being one on each side.

The arrangement of the post a, the knuckle r of the toggle-joint, andthe points of pivotal connection of the toggle-joint with plates c andsupport J is such that when said knuckle is drawn toward post a thesupport is raised,

and when the knuckle passes a line drawn from pin 0 to bolt h the freeend of lever g will rest against thepost, and the sliding support withits load will be sustained independently of the lever For the purpose ofadapting the sliding block J to different heights of axles to a limitedextent without changing the position of pin 0, one end of said supportis formed into a series of steps, 8, which are adapted to receive anordinary steel axle; and for the purpose of engaging large wooden axles,which would not rest properly 011 said narrow steps, the opposite end,if, of the support is made with one broad surface, the intention beingto reverse the support and place said broad surface uppermost in suchcases.

In operation lever f is raised to a vertical position, as showninFig. 1. The sliding support J is then placed under the axle to beraised, and lever f drawn down to the position shown in Fig. 2, thusraising the support and its load and looking it in position, as beforeexplained.

I claim as my invention- 1. Thegrooved vertical post, the foot-piece,the sliding axle-support arranged to engage the grooves in the post, thetoggle-joint, the leverf and rods 1), connecting said lever andtoggle-joint, all combined and arranged to cooperate in the manner andfor the purpose set forth.

2. In a wagon-jack, the combination, with the vertical post, thefoot-piece, and levers g and f, of the pair of curved plates, 0,arranged to form braces for said post and foot-piece, and also supportsfor said levers, substantially as shown and described.

3. In a wagon-jack, the combination, with the grooved vertical post, thefoot-piece, the toggle-joint, and the leverf, of the reversibleaxle-support J, adapted to engage the grooves in the post, and connectedwith'said togglejoint, and having a broad bearing-surface on 5 one endand a series of steps on the opposite end, substantially as and for thepurpose specified.
